To increase amount of income tax flow

It's an issue which I am noticing on an everyday basis that tuition teacher are the ones who earn pure cash income and they pay no income tax on the amount received.

On an average in every locality in Indian (generally Northern region) there is a coaching centre or a tutor who receives all the students of his locality.

Imagine if all these tuition teacher or coaching institutes pay income tax? Our government would have more fund to do it's everyday activities and can invest in education sector of India. Currently it's expenditure on education is too less according to our GDP

I sincerely request you all to sign this petition so that government can do so and we people can live happily in this transformed India.
